While comparing Arfvedsonite and Prase physical properties, the important data you should know is its chemical composition. Since chemical formula defines the molecular structure of the crystal, most of the physical properties like color, tenacity, solubility are governed by Arfvedsonite and Prase chemical formula.
Another important criteria for qualitative analysis of gemstones is Arfvedsonite and Prase Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Arfvedsonite and Prase Optical Properties during the identification of gemstone. Specific gravity of Arfvedsonite is 2.64-2.69 whereas that of Prase is 2.64-2.69.
